Marshall (finger) made his 2014 season debut with Triple-A Louisville on Thursday, the Cincinnati Enquirer reports. He threw 35 pitches (12 strikes) in 1.1 innings against Lehigh Valley, walking five batters and giving up two runs while striking out one and picking up the loss.

Marshall (finger) has increased a throwing program recently, throwing from 90-to-120 feet. "I'm moving faster because it's not an arm issue. It's just a finger issue," Marshall said on Thursday. "My arm is in shape. I was able to keep up my exercises and do everything but throw. Everything feels good."

The 23-year-old Marshall appeared to take a step back in 2013, putting up a 7-10 record with a 5.13 ERA with Triple-A Scranton/Wilkes-Barre. Marshall doesn't have any truly plus offerings, but he offers a mix of four decent pitches that could help him find value as a future back-end starter. The Yankees squeezed him from the 40-man roster in December, but Marshall landed with the Cubs, where he may end up making a handful starts at some point in 2014.
